Answer:
f(x) = 4 - x
Step-by-step explanation:
'f(x) = blah-blah' is the same as saying 'y = blah-blah', except it is also telling you that the x-y relationship is a function.
I notice that for each case, x + y = 4, so y = 4 - x
Or in 'function' terminology, f(x) = 4 - x

Answer:
She will earn $85 in 10 hours.
Step-by-step explanation:
If Rachel earned $34 for 4 hours of work, we must divide the amount earned by the number of hours worked in order to find out her hourly rate and then multiply it by 10 to determine how much she would earn if she worked 10 hours.

She will earn $85 in 10 hours.
To solve an algebraic equation, we need to get x by itself. We can start to do that by multiplying each side of the equation by 62 (to remove the denominator of x).
x + 89(62) = 92 * 62
Simplify
x = 92 * 62 - 89 * 62
Now we can factor out 62
x = 62 (92 - 89)
Now we can simplify the parenthesis
x = 62 * 3
x = 186
